Single tool 'shutup__set_intent' has a basic description (47 chars) and minimal schema. The tool name lacks a clear action verb (set_ is weak for a filtering/intent-setting operation). Input schema is present but sparse: only one required parameter 'intent' with a generic string type and brief description (56 chars). No output schema documented. No error handling guidance. The tool appears to be a control/configuration mechanism rather than a primary agent tool, which limits its utility in a production agent context. Tool definition is visible in shutup/proxy.py but lacks depth expected of production-grade tools.

• Rename tool to 'filter_tools_by_intent' and update description to: 'Filter the available tool list by the user's current task or intent. Call this before listing tools to receive only relevant options. Returns the count of matching tools and a summary of categories.'
• Add explicit output schema documenting returned fields: e.g., {type: 'object', properties: {matched_count: {type: 'integer'}, tool_categories: {type: 'array'}, status: {type: 'string'}}}
• Expand 'intent' parameter description to 20 - 50 words: 'A natural-language description of the user's current task (e.g., "read and write files", "manage GitHub issues"). Used to filter tools via semantic and keyword matching. Required; cannot be empty.'
• Add error handling examples: 'If no tools match the intent, returns empty list with suggestion to broaden intent or list all tools. If intent is empty, returns error: "Intent cannot be empty."'
• Document the tool's role in the proxy workflow: 'This tool configures the proxy's filtering behavior. Typically called once per agent session or when the user's task changes. Does not directly invoke downstream tools.'
